To speak of the Mediterranean Sea as a frontier means, today, to make references to the tensions related to its function of control and regulation of migratory movements; to think of it as the sea “in the middle of lands” means to believe that it represents a political frontier, that is a buffer zone between different realities, separated in cultural, political and above all economic terms. It means to believe that it constitutes a water barrier, in the hope that the pressure from the Southern shore is not so strong, to make it “evaporate”, turning Europe into a sort of peripheral appendix of a big and menacing Eurabia.
